Individual-Level Variables Associated with Self-Efficacy in Nutritional Care for Older People among Italian Nurses: A Multicenter Cross-Sectional Study

Malnutrition in older people is still an unsolved issue. Clinical nurses have a key role in malnutrition prevention. This study aims to describe the individual-level variables associated with self-efficacy in nutrition care for older adults among nurses. A cross-sectional descriptive observational study was performed involving nurses from four northern Italy hospitals. The self-efficacy scale for nursing nutrition care (SE-NNC) and Multiple linear regression (MLR) models were used, enrolling 305 nurses. The mean SE-NNC total score was 53.3 ± 19.7. Considering the three dimensions of the SE-NNC, mean scores were 45.9 ± 21.7 for boosting knowledge, 55.4 ± SD = 20.3 for assessment and evidence utilization, and 57.7 ± 21.1 for care delivery. To be a younger nurse, working in a chronic care setting, and being male were associated with a higher level of self-efficacy, both considering the SE-NNC total score and its dimensions. Working in acute care settings and being an older nurse was associated with lower nursing self-efficacy in nutrition care for older adults.
